目的了解深圳市龙岗中心城区病媒生物的种群和密度,建立病媒传染病的预警体系。方法 2012—2013年在龙岗中心城区选取居民区、医院、公园、工地、餐饮、酒店/旅馆、农贸市场及其周边作为监测点,分别监测蚊、蜚蠊、蝇、鼠等病媒生物。结果龙岗中心城区蚊密度为7.9只/灯,不同监测点蚊密度为公园>工地>医院>居民区,致倦库蚊为优势蚊种,平均布雷图指数为14,蜚蠊密度为2.3只/盒,德国小蠊为优势种;蝇密度为2.35只/笼,家蝇为优势种;鼠密度为3.9%,褐家鼠为优势种。结论结果表明,该地区造成登革热的流行,及时掌握病媒生物的种群及其密度对相应的病媒传染病的防治和疫情处理非常必要,在今后工作中应继续开展长期监测,制定切实可行的预防措施。
Objective To understand the population and density of vector organisms in downtown Longgang, Shenzhen and to establish an early warning system for vector-borne diseases. Methods From 2012 to 2013, residential areas, hospitals, parks, construction sites, restaurants, hotels / guesthouses, farmer’s markets and their surrounding areas were selected as monitoring points in the downtown area of Longgang to monitor vector-borne diseases such as mosquitoes, cockroaches, flies and mice. Results The density of mosquito in downtown Longgang was 7.9 / light. The density of mosquito in different monitoring sites was Park> Site> Hospital> Residential area, Culex pipiens quinquefasciatus was the dominant mosquito species, the average Bretto index was 14 and the cockroach density was 2.3 / The dominant species was Blattella germanica. The density of flies was 2.35 per cage and the dominant species was housefly. The density of rodent was 3.9%, and the dominant species was Rattus norvegicus. Conclusions The results show that it is very necessary to control the prevalence of dengue fever, grasp the population and density of vector organisms in time, and prevent and control the corresponding vector-borne diseases. In the future work, we should continue to conduct long-term monitoring and make feasible Precaution.
